[0035] In the embodiments of the present application, the display screen can be a display screen of a television, an interactive display or a display screen of an education machine, which is determined according to actual needs and is not limited here. The front frame 100 is an aluminum profile, and in other embodiments, the front frame 100 can also be a profile or frame made of other materials; the back plate 200 is connected with the front frame 100 by using connecting screws. The installation space 110 is arranged on the surface of the front frame 100 close to the back plate 200, and the installation space 110 has an installation opening through which the cover glass 300 is installed on the front frame 100; the cover glass 300 is tempered glass, and in other embodiments, the cover glass 300 can also be anti-reflection glass, smart glass or ultraviolet-resistant glass and the like. The liquid crystal panel 400 is located on the side of the cover glass 300 close to the back plate 200. The first connecting structure 600 can be two magnetic blocks used in cooperation, one of which is fixedly installed on the surface of the liquid crystal panel 400 close to the cover glass 300, and the other of which is fixedly installed on the surface of the cover glass 300 close to the liquid crystal panel 400; in other embodiments, the first connecting structure 600 can also be a latch, and the cover glass 300 and the liquid crystal panel 400 are both provided with a hole for the latch to insert. The optical film 500 is located on the side of the liquid crystal panel 400 close to the back plate 200.

[0036] The display screen of the present application is assembled first by using the first connecting structure 600 to connect the liquid crystal panel 400 and the cover plate glass 300, then the cover plate glass 300 with the liquid crystal panel 400 is installed on the front frame 100, and the optical film 500 is installed on the back plate 200, then the back plate 200 is connected with the front frame 100, at this time the cover plate glass 300, the liquid crystal panel 400 and the optical film 500 will be arranged in the installation space 110 in the preset direction in turn. The above design not only helps to reduce the overall thickness and overall volume of the display screen, improve the product quality of the display screen, but also can effectively protect the cover plate glass 300, the liquid crystal panel 400 and the optical film 500, thereby prolonging the service life of the cover plate glass 300, the liquid crystal panel 400 and the optical film 500. In addition, the above design also reduces the number of parts of the display screen, reduces the structural complexity of the display screen, thereby effectively reducing the assembly difficulty and cost of the display screen, and improving the assembly efficiency of the display screen. The first connecting structure 600 is provided to enable the liquid crystal panel 400 to be installed on the front frame 100, thereby enhancing the stability of the liquid crystal panel 400 in the installation space 110.

[0037] Referring to Figure 3 and Figure 4 In an embodiment, the first connecting structure 600 is bonded with the cover plate glass 300 and bonded with the liquid crystal panel 400.

[0038] In the present embodiment, the first connecting structure 600 can be any one of an adhesive component such as double-sided tape, double-sided tape strip or glue. The first connecting structure 600 is provided to not only enable the liquid crystal panel 400 and the cover plate glass 300 to be stably connected, but also to fill the gap between the liquid crystal panel 400 and the cover plate glass 300, thereby reducing the entry of dust, moisture or other pollutants from the outside into the gap between the liquid crystal panel 400 and the cover plate glass 300, thereby prolonging the service life of the display screen. In addition, the above design also helps to simplify the assembly process, improve the assembly efficiency, and reduce the structural complexity and weight of the display screen.

[0039] Referring to Figure 3 and Figure 4 In an embodiment, the first connecting structure 600 is a double-sided tape strip. In the present embodiment, the thickness of the double-sided tape strip ranges from 0.2mm to 2mm, and in a specific embodiment, the thickness of the double-sided tape strip is 1mm. Of course, in other embodiments, the thickness of the double-sided tape strip can also be determined according to actual needs.

[0040] The double-sided adhesive tape not only ensures the stable connection between the liquid crystal panel 400 and the cover glass 300, but also effectively fills the gap between the liquid crystal panel 400 and the cover glass 300, reducing the entry of dust, moisture or other pollutants from the outside into the gap between the liquid crystal panel 400 and the cover glass 300. In addition, since the double-sided adhesive tape has a certain elasticity, it can adapt to temperature changes and small displacements of materials, thereby prolonging the service life of the connection.

[0041] With reference to Figure 3 and Figure 4 In an embodiment, the cover glass 300 covers the liquid crystal panel 400, and the first connection structure 600 is arranged along the circumference of the liquid crystal panel 400.

[0042] In this embodiment, the first connection structure 600 is a ring structure connected head to tail. The above design not only helps to make the display screen thin and light, but also helps to reduce costs. In addition, the above design can effectively fill the gap between the liquid crystal panel 400 and the cover glass 300, avoiding the entry of dust, moisture or other pollutants from the outside into the gap between the liquid crystal panel 400 and the cover glass 300, thereby enhancing the durability and reliability of the display screen.

[0043] With reference to Figure 3 In an embodiment, the liquid crystal panel 400 is attached to the optical film 500. The above design not only helps to reduce light reflection and refraction, improve optical performance, thereby enhancing the display brightness and clarity of the display screen, but also effectively avoids the relative movement of the liquid crystal panel 400 and the optical film 500 by the close attachment of the liquid crystal panel 400 and the optical film 500, so that the liquid crystal panel 400 and the optical film 500 can remain in a relatively static state, reducing the risk of mutual scratching of the liquid crystal panel 400 and the optical film 500 due to vibration. In addition, the above design also effectively reduces the gap between the liquid crystal panel 400 and the optical film 500, reducing glare, reflection and optical distortion, which not only improves the visual experience of the user under different lighting conditions, but also enhances the realism of the image.

[0044] With reference to Figure 2 and Figure 3 In an embodiment, the front frame 100 is provided with a first clamping piece 700 and a second clamping piece 800 arranged at intervals along a predetermined direction, and the cover glass 300 is installed in a clamping area between the first clamping piece 700 and the second clamping piece 800. The first clamping piece 700 applies a clamping force arranged towards the second clamping piece 800 to the cover glass 300 by contacting the cover glass 300, and the second clamping piece 800 applies a clamping force arranged towards the first clamping piece 700 to the cover glass 300 by contacting the cover glass 300.

[0045] In the embodiment, the first clamping member 700 is an infrared filter strip, and is located at the side of the second clamping member 800 close to the front frame 100. The front frame 100 is provided with a mounting groove 120, which is in communication with the mounting space 110. The infrared filter strip is fixedly installed in the mounting groove 120. In other embodiments, the first clamping member 700 can also be other clamping components capable of exerting clamping force on the cover glass 300. The first clamping member 700 is in contact with the first surface of the cover glass 300. The second clamping member 800 is in contact with the second surface of the cover glass 300. The first surface of the cover glass 300 and the second surface of the cover glass 300 are oppositely arranged.

[0046] By using the first clamping member 700 and the second clamping member 800 used in cooperation in the present application, not only can bidirectional clamping force be exerted on the cover glass 300, thereby enhancing the stability of the cover glass 300 in the mounting space 110 and improving the durability and service life of the connection, but also the local stress concentration can be effectively reduced, and the risk of breakage of the cover glass 300 can be reduced. In addition, in order to ensure uniform distribution of clamping force, the first clamping member 700 is kept in close contact with the cover glass 300, and the second clamping member 800 is kept in close contact with the cover glass 300.

[0047] With reference to Figure 2 , Figure 3 and Figure 5 In an embodiment, the second clamping member 800 is located at the side of the first clamping member 700 close to the back plate 200. The second clamping member 800 comprises a clamping portion 810 and a mounting portion 820.

The mounting portion 820 can be detachably mounted on the front frame 100 by means of plug-in, clamping or magnetic attraction. The mounting portion 820 is detachably mounted on the front frame 100. This design not only makes the mounting and dismounting of the second clamping member 800 more convenient, simplifies the assembly and maintenance process, but also enables the mounting position of the second clamping member 800 on the front frame 100 to be adjusted according to requirements, improves the flexibility of mounting, and enables the second clamping member 800 to better adapt to different design requirements. In addition, in order to ensure uniform distribution of clamping force, the clamping portion 810 is kept in close contact with the cover glass 300.

[0049] With reference to Figure 3In an embodiment, the second clamping member 800 further comprises a connecting portion 830, the clamping portion 810 and the mounting portion 820 are connected through the connecting portion 830, and the connecting portion 830 is in contact with the groove wall of the mounting space 110.

[0050] In the embodiment, the clamping portion 810, the connecting portion 830 and the mounting portion 820 are in an integrated structure, and the length direction of the clamping portion 810 is perpendicular to the length direction of the connecting portion 830, and the length direction of the connecting portion 830 is perpendicular to the length direction of the mounting portion 820, so as to facilitate the manufacturing and processing of the second clamping member 800 and ensure the structural strength of the second clamping member 800. The connecting portion 830 not only plays a connecting role, but also plays a role of strengthening the structural strength of the second clamping member 800. In addition, in order to further enhance the stability of the second clamping member 800 in the mounting space 110, the connecting portion 830 is in close contact with the groove wall of the mounting space 110.

[0051] Referring to Figure 3 and Figure 5 In an embodiment, the mounting portion 820 is detachably mounted on the front frame 100 through a connecting component 900.

In other embodiments, the connecting component 900 can also be a fastening pin or a fastening screw.

[0052] Referring to Figure 5 In an embodiment, the number of the second clamping members 800 is multiple, and the multiple second clamping members 800 are arranged at intervals. The multiple second clamping members 800 arranged at intervals help to improve the stability of the cover plate glass 300 in the mounting space 110.

[0053] Referring to Figure 3 , Figure 6 and Figure 7 In an embodiment, the back plate 200 is provided with a limiting structure 1000, and the limiting structure 1000 is in contact with two adjacent side surfaces of the optical film 500 to prevent the optical film 500 from shaking on the back plate 200.

The limiting structure 1000 is arranged to limit the shaking of the optical film 500 on the back plate 200, effectively improving the stability of the optical film 500 on the back plate 200. In addition, in order to strengthen the limiting effect, the number of limiting structures 1000 is four, and the four limiting structures 1000 are respectively arranged in one-to-one correspondence with the four corners of the optical film 500.

[0055] With reference to Figure 3 , Figure 6 and Figure 7 , in an embodiment, the display screen further comprises a diffusion plate 1100, which is located on the side of the optical film 500 away from the liquid crystal panel 400, and is connected to the optical film 500 by a second connecting structure, and is mounted on the back plate 200 by a third connecting structure; the limiting structure 1000 contacts two adjacent sides of the diffusion plate 1100 and can prevent the diffusion plate 1100 from shaking on the back plate 200.

[0056] In the embodiment, the direction of the diffusion plate 1100 to the optical film 500 is parallel to the preset direction. The second connecting structure can be two magnetic blocks used in cooperation, one of which is fixedly installed on the surface of the diffusion plate 1100 close to the optical film 500, and the other of which is fixedly installed on the surface of the optical film 500 close to the diffusion plate 1100; in other embodiments, the second connecting structure can also be a latch, and both the optical film 500 and the diffusion plate 1100 are provided with a hole for the latch to insert. The third connecting structure can be two magnetic blocks used in cooperation, one of which is fixedly installed on the surface of the back plate 200 close to the diffusion plate 1100, and the other of which is fixedly installed on the surface of the diffusion plate 1100 close to the back plate 200; in other embodiments, the third connecting structure can also be a latch, and both the diffusion plate 1100 and the back plate 200 are provided with a hole for the latch to insert.

[0057] The diffusion plate 1100 arranged not only plays a connecting role, allowing the optical film 500 to be stably mounted on the back plate 200, but also can uniformly distribute light, reduce glare and improve color performance. The limiting structure 1000 arranged plays a role in limiting the shaking of the diffusion plate 1100 on the back plate 200, thereby strengthening the stability of the diffusion plate 1100 on the back plate 200.
